Meet Radian 5

Diono's Multi-stage Car Seat

Don’t sacrifice safety for fit
At just 45cm wide, radian 5 provides enhanced side impact protection with aluminum reinforced side walls and reinforced, adjustable head support while saving back seat space vs. some leading competitors. A few centimeters here or there might not sound like a lot, but it could make the difference between a secure 3 across installation or failure to fit all the seats your precious cargo needs.

Family friendly, award-winning combination seat.
Multi-award winning since it entered the market in 2016, Radian 5 is rated among the top narrow car seats & recommended multi-stage seats for parents looking for extended rear facing. Slim profile combination car seats help parents maximize usage by transitioning from rear to forward facing with ease and stretching a single investment over a 10 year product lifespan.

Safety Innovation Wrapped in Comfort
Radian 5 allows for harness usage to 25kg. Plus the unique steel frame and best EPP foam combine to provide the ultimate in side impact protection. Our patented Safe Stop® harness component is a load-limiting device that absorbs energy in a crash. The unique design offers an additional layer of protection by reducing impact to a smaller, forward-facing child.

Side Impact Protection
We’ve got your child’s safety covered. Radian 5 seats feature deep, aluminum reinforced sidewalls that extend straight forward and are lined with thick, energy absorbing foam. We performed rigorous side impact testing to achieve the proper size, shape and strength that best protects children from side impact forces.
